The form name tortuosa describes what immediately strikes anyone who encounters this tree: nothing grows straight. Branches spiral, shoots curl, and even the leaves contort, creating a dense, kinetic winter silhouette that works particularly well reflected in still water. The tree reaches twenty to thirty feet tall with a ten to fifteen foot spread at a characteristically fast willow pace, though it tends toward a shorter life than other willows — a trade-off that seems reasonable given the ornamental payoff.

Contortion is most pronounced on vigorous growth, which means pollarding actually enhances the effect while also keeping the tree compact. Stems cut for flower arrangements hold their sculptural form fresh or dried and are perennially popular for floral use. Site in full sun on moist to wet ground; dry soils will not do. Corkscrew willow is resistant to black walnut and deer, which gives it more placement flexibility than most willows. Keep it well clear of wells, septic systems, and underground infrastructure — the roots are as aggressive as any in the genus.
